To all whom, it may concern;

Be it known that I, W11 ,L IAM S. ELDER, a

delphia, Pennsylvania, have invented certain Improvements in Knitting-Machine N eedles, of which the following is a specification.

The object of my invention is to prevent and other foreign matter in the bottoms of the guide-grooves of knitting-machines having reciprocating which I attain by so constructing the rear face of the ne'edlestem or webholder that it will'because of such reciprocating movement tend to remove and prevent accumulation of such foreign matter in the bottoms of the grooves."

In the accompanying drawings, Figure 1 is aside view, on an enlargedscale, of a knitting machine needle constructed in accordance ,my invention. 2 is a back view of the same, and Fig. 3 is a side view of a we'b-' In ordinary knittin -machines having re-- ciprocatingneedlesoi fine lint, dust,'and other foreign matters accumulate in the needlegrooves and eventually become so packed in the bottoms'of the grooves and form such a hard mass as to constitute what are, in efiect, false bottoms for the grooves, thereby raising the needles from their seats in the grooves and aflecting the character of the stitches produced by the needles, and as these accumulations are greater in some of the needle-grooves than in others the character of the stitches in some of the'wales of the knitted Web Will differ from that of the stitches iii the other wales, and the web will not present a uniform appearance.

I have found-that by notching the rear face of the needle stem or shank such accumulagrooves can be prevented or can be removed after having once accumulated therein, the notches being so shaped as to engage the foreign matterand as the needles are reciprocated move it in one direction or the other until it finally reaches either the outer or the inner end of the needle-groove and is discharged therefrom.

In the drawings I have represented a needle of ordinary construction in which in accordance with my invention each notch has one face of a more abrupt character thanthe Specification of Letters Patent. Application filed May 22.1906. Serial No. 318,150.

other. Thus, as shown, thelosver or inner faces of the notches 1 in the up er or outer portion of the needle stem or -s ank are at the bottoms or inner portions of the notches,

While the abrupt faces of the notches 2 in the lower or inner portion of the shank are at the tops or outer endsof the notches, the consequent effect being that the notches 1 will tend to move to the up er or out'er'end of the needle-groove any in said groove and with which they are caused to engage by the reciprocating movement of the needle, while the lower or inner move such forei oreign matter contained matter to the lower or inner end of the needlegroove. It'is preferablethat the distance between the successive notches in the needleextent of reciproand thus overlap each other,
